摘要：

Amorphous molybdenum sulfide and polypyrrole-tetrathiomolybdate/molybdenum sulfide thin films obtained by electrodeposition from aqueous solutions of ammonium tetrathiomolybdate and pyrrole + ammonium tetrathiomolybdate, respectively, have been characterized by elemental analysis, Auger electron spectroscopy, X-ray photoelectron spectroscopy, infrared spectroscopy, and X-ray absorption spectroscopy. Our data revealed that the structure of electrochemically and thermally produced molybdenum trisulfide are identical but that additional sulfur is also present in the electrodeposited material. On the other hand, polypyrrole films grown in the presence of tetrathiomolybdate as the counterion also contains molybdenum trisulfide. Elemental analysis and X-ray absorption spectroscopy of polypyrrole-tetrathiomolybdate/molybdenum trisulfide thin film suggest that 30% of molybdenum is under the MoS42- form and 70% is present as MoS3.
